METHOD 01F FOR'MING TEXTURE BEIGE.

Application filed October at, 1921. Serial No. smear.

To all whom it may concern:

Be it known' that I, FRANK W. BUTTER- won'rrr, a citizen of the United States, residing at Danville, in the county of Vera milion and State of Illinois, have invented certain new and useful Improvements in Methods of Forming Texture Brick, of which the following is a specification.

This invention relates to a new and im proved method of forming texture bricks and more particularlyto a method of formf in so farv as I am aware, it has not .been

heretofore deemed practical to sand the surface of such bricks. Sanding the surface would lose most of its utility .if the entire surface is thereafter disturbed in forming 3 the texture efiect.

It is an object of the present invention to providea new and improved method of 1forming texture bricks having a sanded suraoe.

It is a further object to rovide such a method wherein the surface 1s sanded prior to the formation'of the texture therein, this formation of the texture not working the entire surface and permitting the sand to m remain upon much of the surface.

' It is an additional object to provide a method of this character which does not require any additional handling or working of the brick or brick-forming material other 4 than that now required in the formation of preferred types of texture brick.

It is also an object to provide a method which is jreadily accomplished by automatic machinery.

5W Other and further objects will appear as the description proceeds.

" Broadly, my invention comprises theextrusion of a brick forming ribbon from dies or the formation of such a ribbon in any 'usual manner and the sanding-0f f Qnb hon.

brick, this stippling ormarhng, however, permitting much ofthe surface to remain undisturbed. The sand is retained upon the undisturbed surface. In its preferable form this stippling is accomplished by means of resilient fingers moved into and out of on gagement with the surface of the brick ribon. Q

I have described in my copending appli- It further involves the stippling or marking of the surface toform a texture cation, Serial No. 449,439, filed March 3,

1921, a method of coloring the surfaces of bricks. In that methdd the coloring matter is worked into the surface of the brick, while the sand in the present case merely adheres to the brick surface.

For accomplishing this stippling or marks ing of the surface of the ribbon, I have found the machine covered by the joint pats, cut to no self and G. Holmes, for Brickmaking mac ine, Patent No. 1,191,925, granted July 18, 1916, to be particularly eficient. I have shown this machine in the accompanying drawings in order to illustrate the application of my method, but it is to be understood that this machine in itself forms,

ventlon. I

undeformed portions of the ll have illustrated certain preferred apparatus for carrying out my method in the accoinpanying drawings, in which i Figure 1 is a plan view of the apparatus;

and

Figure 2 is an end elevation thereof. As shown in the drawings, the machine consists in the conve or 5 adapted to carry the ribbon of brickorming material awa from the die 6 from which it is extrlide Thehardened surface layers of the ribbon are cut away by the wires 8 and the particles of material out by these wires are re-f rnovedl from the ribbon by the plow-shaped member 9. The movable member 10 is carried above the ribbon and isprovided with a large number of resilient steel bristles or fingers 11. This member 10 is provided with a housing 11 adapted to receive an eccentric carried by the shaft 12. The shaft 12 is driven by pulley 13 and is carried by the side members 14 which are connected by the cross members 15 to form a rectangular ra ebi rame is .srpr p wlu 21. The upper arms of these two levers are connected by the rod 22. This construction assures a proper relative movement of the two ends of the member 10. I

A similar pair of members 23 is located adjacent the sides of the ribbon of brickforming material and is operated by the pulley 24 upon the shaft 25.

The sand distributing means 26 is supported from across frame member 15 by straps 27. This member 26 is provided with the screen bottom 28 through which the sand falls upon the ribbon of brick-forming material. The side faces of the brick ribbon are sanded by means of a hopper 29 as shown at the right of Figure 1. This hopper has the peaked bottom 30 adapted to distribute sand to screens 31 located above either side of the ribbon. The blowers 32 are provided to force the falling streams of sand against the sides of the ribbon.

In the operation of the machine, the ribbon of brick-forming material is extruded from the dies 6, is trimmed by the wires 8 and cleaned by the plow 9. Sand is then dropped on the ribbon of material and as the ribbon passes under the member 10 with its fingers 11, this member 10 moves toward and away from the ribbon and also longitudinally in the direction taken by the ribbon, the member being actuated bythe'eccentric cam rotated by pulley 13. These spring'fingers or bristles engage the surface of the material and stipple that surface, and form it with a plurality of short lines. Due to the resilience of the fingers or bristles they are bent as they engage the ribbon and as they move away from the ribbon in the actuation of the member 10, their resilience causes them to straighten and in so doing they pick small particles from the surface of materiaL,

The sides of the ribbon have sand blown thereon with sufiicient force so that the sand adheres to the damp surface. This surface is worked by the operation of the bristles upon the members 23 in a manner similarto the working-of the top surface. It is to be understood that this working is not suchas to roughen the entire surface of the material. The stippling has smooth, unworked spaces between the markings and these spaces retain the-sand i comprising applying sand to the surface thereof and thereafter stippling said surface.
